IIWPROVIELlVIIl-lNT IN SABE-ROPE vGUIDES.

The Schedule referred to in these Letters Patent and making part of the same To all persons to whom these presents may come VBe it known that I, WINSLOW W. FIFIELD, of Medford, in the county of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in Sash-Rope Guides for window-trames; and do herebyl declare the. same to be fully described in the following specification, and lrepresented in the accompanying drawings, of which- Y Figure l denotes a side elevation,

Figure 2, a front-end View,

Figure 3, a rear-end view, and

Figure 4, 'a longitudinal section of a rope-guide as made in accordance with my invention.

The'body-part A of the guide is a cylindrical tube, provided with a male screw,a, formed on it near and from its front end.

The lower half or part of the bore b, of the tube, is rounded or curved down at each end, as shown at d and e, the same Causing the front part of the said bore to terminate in an elongated mouth, f.

There projects from the front end of the body, and around the whole or the lower part of the mouth, an extension or lip, g, whose purpose is to prevent the suspension-rope ofthe sash, while going through and depending from the guide, from coming into contact with thevpulley-stick or window-frame, and thereby becoming worn or abraded thereby, while the sash may be in movement. t 1 v rlhe length of the body is such as to cause it, when screwed into a pulley-stile of a window-trame, to project in rear thereof', a distance somewhat greater than the diameter or width of the counterbalance-Weight to he suspended from the rope, the purpose of such extension being to keep the weight from contact with the rear face of the pulley-stile,whi1e the said weight may he in vertical movement. Figure 5 exhibits a section of a pulley-stile with the guide applied to it, and with the rope and .Weight depending from the guide, such ligure being to show how the guide, when in use, projects back ot' the stile ln this iigure, S is the stile, R, the ropehw, the weight, and P, the part projected back of the stile.

The article or rope-guide above described "is ydesigned to be made of glass, porcelain, or other suitable material, and to be formed in one piece.

When used, it is to'be screwed into a hole bored for its reception in the pulley-stile, or part of the Window-frame or article designed toV receive it.

The elongated mouth of the bore enables aperson, by` means of a key or proper implement, when inserted within and fitted to such month, to e'ect either the screwing of the guide intothe window-frame, or the unscrewing of it therefrom, as occasion may require.

I claim, as my invention- The sash-rope guide, as made with the screw o, and the rope-passage b arranged on itas described, and with the elongated mouth f, to the rope-passage b, andthe lip q upon the lower side of the opening, such being substantially as and for the purposes as hereinbefore explained.
